Teensy 4.0 not running as expected

[daemoncibsec]

Hello anyone reading this. I recently bought a Teensy for a cybersecurity project and it was actually going pretty well. Though I'm indeed satisfied with the product itself, I'm recently having issues running Arduino code on Teensy's keyboard interface. I'm trying to open the notepad in Windows to type something as a test, but it only prints part of the text I want it to type. I've read about this and have heard something about last model Teensy having issues with memory cells. Could this be the cause or may it be the code?

If mor information is needed, I'm more than glad to help. I just want to prank a friend to convince him so he helps me with the project, but for that I need a demonstration of what I want to do and I'm actually having problems with Teensy as I said, so I'd be grateful if anyone could help me with this. Thanks for your time.

To be honest, I have no idea what you mean by this. Also, I'm not sure what you want to show us with the attached screenshot?
Could you share the code that shows the issue and elaborate on what you want to achieve?

Do you perhaps have a source for this?

I presume its being used as a USB keyboard - perhaps you have a bug in your code - can you show us the code?

Try having Teensy send the message to different software. Try "simple" programs like Notepad or a command prompt window. This problem may turn out to be a simple matter that some programs are just too slow to receive characters this quickly.

Hello everyone, I'm sorry about answering so late, but I've been busy recently. Speaking about the code, I'm using a USB keyboard indeed, and I'm trying it to print a "Hello World" ASCII art by opening notepad. The ASCII art should look like this:

But it actually prints the message like this:

Which is not the result I'm searching for. The interesting part is that, when I unplug the Teensy USB keyboard, and plug it again, it show a different result printing the ASCII art, but still isn't what I'd expect.

I'll leave here the code so that you can tell me if you see some issue with it. It's most probable the code is the thing isn't functioning properly, since I don't know a lot about Arduino languaje, but I have intererst on learning and trying to program something for myself. Anyways, here's the code:

No Code!

I'm sorry, I'm so ashamed. I had to send it apart because of an error on my last post. It's actually waiting for the approval of a moderator to send the code. When it's sent you'll see it, but thanks for attention!
